Evaluation pré-post d'une intervention de prévention du VIH auprès des hommes qui ont des rapports sexuels avec des hommes, Suisse 2012

Contexte: L'intervention "Break The Chains" 2012 de l'OFSP a l'intention des gays visait à informer sur la primo-infection et a inciter a un test de dépistage VIH. Design: L'évaluation a recouru a un design Pre-Post avec 2 dispositifs: A) enquête par questionnaire Internet avec une vague avant la campagne et une après (transversal repete); B) 1) relevé centré sur le canton de Zurich du nombre de test effectues par des gays durant le premier semestre 2012 utilisant des données récoltées par Sentinella, par les centres de test utilisant l'application BerDa et auprès des praticiens de HIV-Prakt; et 2) recueil d'information par le questionnaire internet post-intervention des intentions d'effectuer un test VIH. Résultats: 366 HSH ont répondu au questionnaire de la phase pré-, et 964 à la phase post-intervention. 69.8% ont entendu parler de la campagne. Parmi les répondants ayant identifie le message, 48.6% se sont sentis concernes. Avant la campagne, 34.2% des répondants identifiaient les 4 symptômes de la primo-infection, 46.4% se sentaient bien informes et 79.2% connaissaient le délai minimum pour qu'un test informe sur une absence d'infection; après la campagne, ces proportions étaient 39.6%, 62.0% et 85.2%. 17.1% des répondants ont déclaré avoir fait/avoir l'intention de faire, un test VIH suite à la campagne. Le nombre de tests effectues par les répondants Internet montre effectivement un pic dans le 2e trimestre 2012; les données BerDa montrent une stabilité du nombre total de tests. Les données épidémiologiques montrent une augmentation de la proportion et du nombre d'infections récentes détectées durant ce 2e trimestre, mais une diminution des infections anciennes. Conclusions: L'intervention BTC a amélioré légèrement les connaissances relatives à la phase de primo-infection du VIH et a la nécessité d'effectuer un test VIH. Elle semble avoir incite le public cible à effectuer un test VIH qui n'aurait pas été réalisé autrement et a peut-être ainsi contribuer a la détection d'infections récentes.

Community pharmacist intervention in depressed primary care patients (PRODEFAR study): randomized controlled trial protocol.

Background: Treatment of depression, the most prevalent and costly mental disorder, needs to be improved. Non-concordance with clinical guidelines and non-adherence can limit the efficacy of pharmacological treatment of depression. Through pharmaceutical care, pharmacists can improve patients' compliance and wellbeing. The aim of this study is to evaluate the effectiveness and costeffectiveness of a community pharmacist intervention developed to improve adherence and outcomes of primary care patients with depression. Methods/design: A randomized controlled trial, with 6-month follow-up, comparing patients receiving a pharmaceutical care support programme in primary care with patients receiving usual care. The total sample comprises 194 patients (aged between 18 and 75) diagnosed with depressive disorder in a primary care health centre in the province of Barcelona (Spain). Subjects will be asked for written informed consent in order to participate in the study. Diagnosis will be confirmed using the SCID-I. The intervention consists of an educational programme focused on improving knowledge about medication, making patients aware of the importance of compliance, reducing stigma, reassuring patients about side-effects and stressing the importance of carrying out general practitioners' advice. Measurements will take place at baseline, and after 3 and 6 months. Main outcome measure is compliance with antidepressants. Secondary outcomes include; clinical severity of depression (PHQ-9), anxiety (STAI-S), health-related quality of life (EuroQol-5D), satisfaction with the treatment received, side-effects, chronic physical conditions and sociodemographics. The use of healthcare and social care services will be assessed with an adapted version of the Client Service Receipt Inventory (CSRI). Discussion: This trial will provide valuable information for health professionals and policy makers on the effectiveness and cost-effectiveness of a pharmaceutical intervention programme in the context of primary care. Trial registration: NCT00794196

Recommendations on percutaneous coronary intervention for the reperfusion of acute ST elevation myocardial infarction

Little information is currently available from the various societies of cardiology on primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). Since primary PCI is the main method of reperfusion in AMI in many centres, and since of all cardiac emergencies AMI represents the most urgent situation for PCI, recommendations based on scientific evidence and expert experience would be useful for centres practising primary PCI, or those looking to establish a primary PCI programme. To this aim, a task force for primary PCI in AMI was formed to develop a set of recommendations to complement and assist clinical judgment. This paper represents the product of their recommendations.

Effectiveness of a brief integrative multiple substance use intervention among young men with and without booster sessions.

Brief interventions (BI) commonly employ screening and target a single substance. Multi-substance interventions are a more adequate reflection of risk behaviors in adolescents and young adults. Systematic screening complicates BI in many settings. The effectiveness of a voluntary multi-substance intervention among 19-year-old men and the incremental impact of booster sessions were analyzed. Participants were enrolled during mandatory army conscription in Switzerland. Compared with 461 controls, 392 BI subjects showed reduced substance use on 10 of 12 measures (4 tobacco, 4 cannabis, and 2 alcohol measures). Between-group effects were small and non-significant (except for cannabis use prevalence). Three-month booster sessions were not effective and even contraindicated. The usefulness of targeting multi-substances during BIs without prior screening depends on the value of small effects. The addition of booster sessions was not effective and therefore is not recommended.

Early antifungal intervention strategies in ICU patients.

PURPOSE OF REVIEW: Despite progress in the understanding of the pathophysiology of invasive candidiasis, and the development of new classes of well tolerated antifungals, invasive candidiasis remains a disease difficult to diagnose, and associated with significant morbidity and mortality. Early antifungal treatment may be useful in selected groups of patients who remain difficult to identify prospectively. The purpose of this review is to summarize the recent development of risk-identification strategies targeting early identification of ICU patients susceptible to benefit from preemptive or empirical antifungal treatment. RECENT FINDINGS: Combinations of different risk factors are useful in identifying high-risk patients. Among the many risk factors predisposing to invasive candidiasis, colonization has been identified as one of the most important. In contrast to prospective surveillance of the dynamics of colonization (colonization index), integration of clinical colonization status in risk scores models significantly improve their accuracy in identifying patients at risk of invasive candidiasis. SUMMARY: To date, despite limited prospective validation, clinical models targeted at early identification of patients at risk to develop invasive candidiasis represent a major advance in the management of patients at risk of invasive candidiasis. Moreover, large clinical studies using such risk scores or predictive rules are underway.

Effect of a lifestyle intervention on adiposity and fitness in socially disadvantaged subgroups of preschoolers: a cluster-randomized trial (Ballabeina).

OBJECTIVE: A multidimensional lifestyle intervention performed in 652 preschoolers (72% of migrant, 38% of low educational level (EL) parents) reduced body fat, but not BMI and improved fitness. The objective of this study is to examine whether the intervention was equally effective in children of migrant and/or low EL parents.¦METHODS: Cluster-randomized controlled single blinded trial, conducted in 2008/09 in 40 randomly selected preschools in Switzerland. The culturally tailored intervention consisted of a physical activity program and lessons on nutrition, media use and sleep. Primary outcomes included BMI and aerobic fitness. Secondary outcomes included %body fat, waist circumference and motor agility.¦RESULTS: Children of migrant parents benefitted similarly from the intervention compared to their counterparts (p for interaction≥ 0.09). However, children of low EL parents benefitted less, although these differences did not reach statistical significance (p for interaction≥ 0.06). Average intervention effect sizes for BMI were -0.10, -0.05, -0.11 and 0.04 kg/m(2) and for aerobic fitness were 0.55, 0.20, 0.37 and -0.05 stages for children of non-migrant, migrant, middle/high EL and low EL parents, respectively.¦CONCLUSIONS: This intervention was similarly effective among preschoolers of migrant parents compared to their counterparts, while children of low EL parents benefitted less.

Native Grassland Conversion: the Roles of Risk Intervention and Switching Costs

We develop a real option model of the irreversible native grassland conversion decision. Upon plowing, native grassland can be followed by either a permanent cropping system or a system in which land is put under cropping (respectively, grazing) whenever crop prices are high (respectively, low). Switching costs are incurred upon alternating between cropping and grazing. The effects of risk intervention in the form of crop insurance subsidies are studied, as are the effects of cropping innovations that reduce switching costs. We calibrate the model by using cropping return data for South Central North Dakota from 1989 to 2012. Simulations show that a risk intervention that offsets 20% of a cropping return shortfall increases the sod-busting cost threshold, below which native sod will be busted, by 41% (or $43.7/acre). Omitting cropping return risk across time underestimates this sod-busting cost threshold by 23% (or $24.35/acre), and hence underestimates the native sod conversion caused by crop production.

Circadian Variations of Ischemic Burden Among Patients with Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention

Introduction Le rythmes circadiens influencent différents paramètres de la physiologie et de la physiopathologie cardiovasculaire. Récemment, une relation entre la taille d'un infarctus et l'heure du jour à laquelle il se produit a été suggérée dans des modèles expérimentaux d'infarctus du myocarde. Le but de cette étude a été de déterminer si les rythmes circadiens pouvaient influencer la gravité d'un infarctus en terme de taille et de mortalité chez les patients hospitalisés pour un infarctus du myocarde avec sus-décalage du segment ST (STEMI) ayant bénéficié d'une intervention coronarienne percutanée primaire (ICPP). Méthode Chez 353 patients consécutifs admis avec un STEMI et traités par ICPP, l'heure à la survenue des symptômes, le pic de créatine kinase (reflet de la taille d'un infarctus) et le suivi à 30 jours ont été collectés. Les patients ont été répartis en 4 groupes en fonction de l'heure de survenue de leurs symptômes (00 :00 - 05h59, 06:00 - 11 59 12 00-17h59 et 18h00-23h59). Résultats Aucune différence statistiquement significative n'a été retrouvée entre les différents groupes en ce qui concerne les caractéristiques des patients ou de leur prise en charge. Après analyse multivariée, nous avons mis en évidence une différence statistiquement significative entre les pics de créatine kinase chez les patients avec survenue des symptômes entre 00 :00 et 05:59, qui étaient plus élevés que les pics de créatine kinase chez les patients avec survenue des symptômes à tout autre moment de la journée (augmentation moyenne de 38,4%, ρ <0.05). A 30 jours, la mortalité des patients avec survenue des symptômes entre 00 :00 et 05:59 était également significativement plus élevé que celle des patients avec survenue à tout autre moment de la journée (p <0.05). Conclusion Notre étude démontre une corrélation indépendante entre la taille d'un infarctus STEMI traité par ICPP et le moment de la journée où les symptômes apparaissent. Ces résultats suggèrent que ce moment devrait être un paramètre important à prendre en compte pour évaluer le pronostic des patients.

Public health significance of bipolar disorder: implications for early intervention and prevention.

OBJECTIVES: Early intervention and preventive strategies have become major targets of research and service development in psychiatry over the last few years. Compared to schizophrenia, bipolar disorder (BD) has received limited attention in this regard. In this paper, we review the available literature in order to explore the public health significance of BD and the extent to which this may justify the development of early intervention strategies for this disorder. METHODS: The main computerized psychiatric literature databases were accessed. This included Medline and PsychInfo, using the following keywords: bipolar, early intervention, staging model, burden, caregiver, public health, and manic depression. RESULTS: BD is often recurrent and has an impact that goes well beyond symptomatic pathology. The burden it incurs is linked not only to its cardinal clinical features, but also to cognitive dysfunction, poor functional outcome, poor physical health, high rate of comorbidities, and suicide. At a societal level, BD induces enormous direct and indirect costs and has a major impact on caregivers. The available literature reveals a usually long delay between illness onset and the start of treatment, and the absence of specific guidelines for the treatment of the early phase of BD. CONCLUSIONS: Considering the major impact of BD on patients and society, there is an urgent need for the development of early intervention strategies aimed at earlier detection and more specific treatment of the early phase of the disorder.

Influence of socioeconomic factors on delays, management and outcome amongst patients with acute myocardial infarction undergoing primary percutaneous coronary intervention.

The outcome after primary percutaneous coronary intervention (pPCI) for ST-elevation myocardial infarction (STEMI) is strongly affected by time delays. In this study, we sought to identify the impact of specific socioeconomic factors on time delays, subsequent STEMI management and outcomes in STEMI patients undergoing pPCI, who came from a well-defined region of the French part of Switzerland. A total of 402 consecutive patients undergoing pPCI for STEMI in a large tertiary hospital were retrospectively studied. Symptom-to-first-medical-contact time was analysed for the following socioeconomic factors: level of education, origin and marital status. Main exclusion criteria were: time delay beyond 12 hours, previous treatment with fibrinolytic agents or patients immediately referred for coronary artery bypass graft surgery. Therefore, 222 patients were finally included. At 1 year, there was no difference in mortality between the different socioeconomic groups. Furthermore, there was no difference in management characteristics between them. Symptom-to-first-medical-contact time was significantly longer for patients with a low level of education, Swiss citizens and unmarried patients, with median differences of 23 minutes, 18 minutes and 13 minutes, respectively (p <0.05). Nevertheless, no difference was found regarding in-hospital management and clinical outcome. This study demonstrates that symptom-to-first-medical-contact time is longer amongst people with a lower educational level, Swiss citizens and unmarried people. Because of the low mortality rate in general, these differences in delays did not affect clinical outcomes. Still, tertiary prevention measures should particularly focus on these vulnerable populations.

Intervention of carbonate components in petrogenesis of the pyroxene nephelinites from the Jbel Saghro (Anti-Atlas, Morocco)

The Jbel Saghro alkaline complex was emplaced close to the eastern edge of the Moroccan Anti-Atlas. Within the northern part, two types of nephelinite were recognized [Ibhi and Nachit, 1999 and lbhi, 2000]. The first type (olivine-rich nephelinite) constitutes the main volcanic mass south of the Bou Gafer granit (fig. 1), where the volcanism had been active at least during 2 Ma, between 9.6 and 7.5 +/- 0.1 Ma [Berrahma et al., 1993]. The second group outcrops in the north (Foum El Kouss). It consists of pyroxene nephelinites which are younger (2.9 +/- 0.1 Ma) [Berrahma et al., 1993], and bears carbonatitic xenoliths, melteigitic pyroxenites and metasomatised peridotite xenoliths. Geochemically, the pyroxene nephelinite is highly enriched in LILE compared with the first one. The mineralogical and geochemical characteristics may be explained by the incorporation of carbonatitic and melteigitic pyroxenite segregates of carbonatitic affinity.
